A total of 234 individual silver-lipped pearl oyster (Pillctada maxima) from six populations in Australia and two populations in Indonesia were analyzed for genetic variation within a 6S0-base pair region of the mitochondrial DNA COl gene using restriction fragment length polymorphism analysis. The Indonesian populations were markedly different from all Australian populations examined, and the differences were greater than that expected on the basis of their geographical separation. In contrast with this broader regional pattern of genetic differentiation, the Australian populations sampled were not significantly differentiated from one another, and a high degree of connectivity was observed among Western Australian pearl oyster populations. In addition. these genetic data show that Western Australian P. maxima populations have a closer tie to those from the northern Australian coast than with populations in Indonesia. This regional pattern of genetic separation is evident despite the proximity of Indonesia to the eastern Indian Ocean locations sampled and the potential for dispersal afforded by the southward currents of the Indonesian throughflow.
